A CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and
some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough water. You don’t
need to add water to the Delco Freedom@ battery
installed in every new
GM vehicle. But if a
battery has filler caps, be sure the right amount
of fluid is there. If it is low, add water to take care
of that
first. If you don’t, explosive gas could be
present.
Battery fluid contains acid that can burn you.
Don’t get it on you.
If you accidentally get it in
your eyes
or on your skin, flush the place with
water and get medical help immediately.
6. Check that the jumper cables don’t have loose or
missing insulation. If they do, you could get a shock.
The vehicles could also be damaged.
Before you
connect the cables, here are some things
you should know. Positive (+) will go to positive (+)
and negative (0) will go to negative (-) or a metal
engine
part. Don’t connect positive (+) to negative (-)
or you’ll get a short that would damage the battery and
maybe other parts, too.
A CAUTION:
- - -~
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engines are running.

You will find an ENGINE COOLANT HOT-IDLE
ENGINE message
or a STOP ENGINE ENGINE
OVERHEATED message on the DIC. There is also an
engine temperature warning light
on the instrument
panel. See “Engine Temperature Warning Light” in the
Index.
Overheated Engine Protection Operating
Mode
Y
Should a low coolant condition exist and the message
STOP ENGINE
ENGINE OVERHEATED is displayed,
an overheat protection mode which alternates firing
groups
of four cylinders helps prevent engine damage.
This operating mode
allows your vehicle to be driven
to a safe place in
an emergency; you may drive up to
50 miles (80 km). Towing a trailer in the overheat
protection mode should be avoided.
I NOTICE:
After driving in the Overheated Engine
Protection Operating Mode,
to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil may be
severely degraded. Change the
oil and reset the
oil life indicator. See “Engine Oil, When to
~ Change” in the Index.

I NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well
as the tires. If you spin the wheels
too fast while shifting your transaxle back and
forth,
you can destroy your transaxle.
For information about using tire chains on your vehicle, see “Tire Chains” in the Index.
Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will
clear the
area around your front wheels. You should
1 your traction control system off. (See “Traction Control
1 System” in the Index.) Then shift back and forth
between
REVERSE (R) and a forward gear, spinning the
1 wheels as little as possible. Release the accelerator pedal
~ while you shift, and press lightly on the accelerator
pedal when fie transaxle
is in gear. If that doesn’t get
you out after a
few tries, you may need to be towed out.
If you do need to be towed out, see “Towing Your
Vehicle’’ in the Index.

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your vehicle for
5 years or 100,000 miles (166 0o0 km),
whichever occurs first.
The following explains your cooling system and how
to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating” in
the Index.
A 50/50 mixture of water and the proper coolant for
your Cadillac will:
Give freezing protection down to -34°F (-37 O C).
Give boiling protection up to 265 “F (129 “C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant
will require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.
What
to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need
to add anything else.
A special procedure is required for adding sealer; see the
Cadillac service manual.
(To order a service manual, see
“Service and Owner Publications”
in the Index.)

.
The surge tank is located next to the engine block on the
passenger’s side of the engine.
The cooling system when hot is under a lot of pressure.
If the CHECK COOLANT LEVEL message appears on
the
DIC, you will’need to add coolant.
A CAUTION:
I’urning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly. Never turn the surge tank pressure cap
-- even a
little
-- when the engine and radiator are hot.
When your engine is cold, the coolant level should be
at the full cold mark, which is 2.5 inches (60 mm) below
the
base of the fill neck. Use a flashlight as necessary to
see into the tank.

Brake Fluid

Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake
fluid goes down
to an acceptable level during normal
brake lining
wear. When new linings are put in, the fluid
level goes
back up. The other reason is that fluid is
leaking out of
the brake system. If it is, you should have your brake system fixed, since
a leak means that sooner
or later
your brakes won't work well, or won't work
at all.
So, it isn't a good idea to "top off' your brake fluid.
Adding brake fluid won't correct
a leak. If you add fluid
when
your linings are worn, then you'll have too much
fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is
done on
the brake hydraulic system.
I A CAUTION:
If you have too much brake fluid, it can spill on
the engine. The fluid will burn if the engine
is hot
enough. You or others could be burned, and your
vehicle could
be damaged. Add brake fluid only
when work
is done on the brake hydraulic system.
When your brake fluid falls to a low level, your brake
warning light will come on. See "Brake System Warning
Light"
in the Index.

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
Continuing to drive with worn-out brake pads
could result
in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied
or lightly
applied. This does not mean something is wrong with
your brakes.
Free movement of brake calipers and proprely torqued
wheel nuts are necessary
to help prevent brake
pulsation. When tires are rotated, inspect brake calipers
for movement, brake pads for wear, and evenly torque wheel nuts in the proper sequence to
GM Specifications.
Brake linings should always
be replaced as complete
axle sets.
Brake Pedal Travel Brake Adjustment
Every time you apply the brakes, with
or without the
vehicle moving,
your brakes adjust for wear.
Replacing Brake System Parts
The braking system on a modem vehicle is complex.
Its many parts have to
be of top quality and work well
together if the vehicle
is to have really good braking.
Vehicles
we design and test have top-quality GM brake
parts in them, as your Cadillac does when it is new.
When you replace
parts of your braking system -- for
example, when your brake linings wear down and you
have to have new ones put in
-- be sure you get new
genuine
GM replacement parts. If you don’t, your
brakes may no longer work properly. For example, if
someone puts in brake linings that are wrong for your
vehicle, the balance between your front and rear brakes
can change -- for the worse. The braking performance
you’ve come to expect can change in many other ways if
someone puts in the wrong replacement brake
parts.
--
See your dealer if the brake pedal does not return to
normal height,
or if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have a crash.
Using tires of different sizes
may also cause
damage to your vehicle. Be sure
to use the same
size
and type tires on all four wheels.
It’s all right
to drive with your compact spare,
though. It
was developed for use on your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This applies only to vehicles sold
in the United States.) The
grades are molded on the sidewalls
of most passenger
car tires. The Uniform Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary
use spare tires, tires with
nominal rim diameters of 10 to 12 inches (25 to 30 cm),
or
to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may
vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria
(TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course.
For
example, a tire graded 150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded
100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.

surrounding trim along stitch
or welt lines.
Mix Multi-Purpose Powdered Cleaner following the
directions on the container label.
Use suds only and apply with
a clean sponge.
Don’t saturate the material.
Don’t rub it roughly.
As soon as you’ve cleaned the section, use a sponge
to remove the suds.
Rinse the section with a clean, wet sponge.
Wipe
off what’s left with a slightly damp paper towel
or cloth.
Then dry it immediately with a blow dryer.
Wipe with
a clean cloth.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at dl.
Some spots and stains will clean off better with just
water and mild soap.
If you need to use a solvent:
Gently scrape excess soil from the trim material with
a clean, dull knife or scraper. Use very little cleaner,
light pressure
and clean cloths (preferably
cheesecloth). Cleaning should start at the outside
of
the stain, “feathering” toward the center. Keep
changing to a clean section of the cloth.
0 When you clean a stain from fabric, immediately
dry the area with a blow dryer to help prevent a
cleaning ring.
